Metabolite prediction

Based on yesterday's oral arguments in LabCorp v. Metabolite, Harold Wegner predicts the likelihood that Justice Stevens will write the majority opinion and that this opinion will reverse and remand the case to the Federal Circuit. That court had held that the patent claim combining a scientific discovery with a prior art blood test was patentable.

My observation is that if Stevens,who wrote the old anti-software-patent opinion in Parker v. Flook, keeps to his old (and the Supreme Court's old) philosophy regarding subject matter patentability, and extends his comments beyond "laws of nature" to other expressly forbidden categories (one of which is "algorithms"), there will be fireworks for business method patents and even software patents. Even if the Court applies a Flook-type methodology without expressly excluding algorithms from the scope of its argument, this could set a very big precedent that could be used to attack software and business method patents.

If Flook is applied in this way to reverse Metabolite, thus creating uncertainty about the validity of software and business method patents, expect a hue and cry among corporate lobbyists here on K Street, resulting in legislation to expressly designate software, business methods, or both as patentable categories of subject matter.

There are, however, several other possible rationales for invalidating the patent in Metabolite, so Stevens may have a hard time gathering five votes to apply the Flook methodology here. Expect the Court's decision in June.

"Like most blogs worth my attention, this blog is updated only infrequently. That is because the authors of blogs worth my attention only post when they have something to say that is true, relevant and not already known by their audience. Most of the human race does not have the skill to know when an idea has these three properties. The skill is particularly rare in the fields of politics and economics, which is why this blog is such a rare and valuable thing." -- Richard Hollerith
